The sun had set four years ago and had not risen since.
But the time would be coming soon when it would lift over the horizon again. Within a few short months it would once more sear the planet's surface with its blue-white rays. But until that happened the endless twilight prevailed and, in that half-light, the great ears of mutated corn grew rich and full. A single crop, a sea of yellow and green that stretched to the horizon in all directions--except one. Here the field ended, bounded by a high metal fence, and beyond the fence was the desert. A wasteland of sand and gravel, a shadowless and endless plain that vanished into dimness under the twilight sky. No rain fell here and nothing grew here--in sharp contrast to the burgeoning farmland beyond. But something lived in the barren plains, a creature that found its every need in the sterile sands.
The flattened mound of creased gray flesh must have weighed at least six tonnes. There appeared to be no openings or organs in its upper surface, although close examination would have revealed that each of the nodules in the thick skin contained a silicon window that was perfectly adapted to absorb radiation from the sky. Plant cells beneath the transparent areas, part of the intricate symbiotic relationships of the lumper, transformed the energy into sugar. Slowly, sluggishly,by osmotic movement between cells, the sugar migrated to the lower portion of the creature, where it was transformed into alcohol and stored in vacuoles until needed. A number of other chemical processes were also taking place on this lower surface at the same time.
The lumper was draped over a particularly rich outcropping of copper salts. Specialized cells had secreted acid to dissolve the salts, which had then been absorbed. This process had been going on for a measureless time, for the beast had no brain recognizable as such, or any organs to measure time with. It existed. It was here, eating, cropping the minerals as a cow would grass. Until, as in a grazed field, the available supply of food was gone. The time had come to move on. When the supply of nourishment fell away, chemoreceptors passed on their messages and the thousands of leg muscles in the lumper's ridged lower surface began to retract. Fueled now by the carefully stored alcohol, the muscles were actuated in a single, orgasmic spasm that sent the six tonnes of thick, carpetlike hulk hurtling over thirty meters through the air.
It cleared the fence that ringed the farm, and fell with an immense thudding impact into the two-meter high Gammacorn, crushing it flat, vanishing from sight behind the screen of green leaves and arm-long, golden ears. At its thickest point the lumper was only a meter through, so it was completely hidden from the view of the other creature that rumbled toward it.
Neither of them had a brain. The six-tonne organic beast was controlled completely by the reflex arcs that it had been born with some centuries earlier. The metallic creature weighed twenty-seven tonnes, and was controlled by a programmed computer that had been installed when it was built. Both of them had senses--but were not sentient. Each was totally unaware of the other until they met.
The meeting was very dramatic. The great form of the harvester approached, clanking and whirring industriously. It was cutting a swathe thirty meters widethrough the evenly aligned rows of corn that marched away to the horizon. In a single pass it cut the corn, separated the ripe ears from the stalks, chopped the stalks to small bits, then burnt the fragments in a roaring oven. The water vapor from this instant combustion escaped from a high chimney in white trails of vapor, the ash billowed out in a black cloud from between the clanking treads to settle back to the ground. It was a very efficient machine at doing what it was supposed to do. It was not supposed to detect lumpers hidden in the corn field. It ran into the lumper and snapped off a good two hundred kilos of flesh before the alarms brought it to a halt.
As primitive as its nervous system was, the lumper was certainly aware of something as drastic as this. Chemical signals were released to activate the jumping feet and within minutes, incredibly fast for a lumper, the muscles contracted and the beast jumped again. It wasn't a very good leap though, since most of the alcohol had been exhausted. The effort was just enough to raise it a few meters into the air to land on top of the harvester. Metal bent and broke, and many more alarm signals were tripped to add to the ones already activated by the beast's presence.
Wherever the gold plating of the harvester had been torn or scratched away the lumper found toothsome steel. It settled down, firmly draped over the great machine, and began placidly to eat it.
